für Deine Spende"). Ruins of Hirschstein On the northern path between the station of Kirchenlamitz-Ost and the Kornberg summit lies the rock castle (Felsburg) of Hirschstein (). It is the site of a former castle of which only a few remains are still visible. The castle is one of the oldest in the Fichtelgebirge, is believed to have belonged in 1206 to Rüdiger and Utzo von Hirzberg zen Herschenstein (of the family of Hirschberg). However it does not appear in the records until 1317. At that time Count Berthold of Henneberg enfeoffed the hus on the Kurnberg to the five brothers, the Hirzbergers, Herr Heinrich, Fridrich, Arnolt, Eberhart and Heymann and others. Around the middle of the 14th century the castle was destroyed, because in 1361 Burgrave Frederick of Nuremberg allowed the Hirschbergs to rebuild the castle. However, it was never rebuilt. During the Thirty Years' War the ruins and vaults of the old castle were used by the local countryfolk as a refuge. By margravial order the vaults were filled with rubble in the 18th century because gypsies and other shady characters had squatted there. Gypsy Rocks The granite rock outcrop known as Gypsy Rocks (Zigeunerfelsen), a fine example of spheroidal weathering, lies on the western slopes of the Kornberg, on the northern path (Nordweg) from Kirchenlamitz-Ost station to the summit. The largest block is about nine metres long, four to seven metres wide and two metres high; it weighs about 250 tonnes. A rock with the name Wackelstein is a rocking stone and can be made to rock with a wooden beam. The area is believed to have offered hordes of gypsies a refuge in times gone by. During the Thirty Years' War the inhabitants of the area took shelter here. Former Bundeswehr surveillance tower The Kornberg summit is dominated by the military surveillance tower built in 1973 for the Bundeswehr and taken into service in 1976. During the Cold War it acted as a listening post, picking up military radio traffic by the land forces of the Warsaw Pact. The tower was run by the 946th Signals Company (Fernmeldekompanie 946), which was stationed in Hof/Saale. After the withdrawal of Soviet troops from the former East Germany in 1994 the tower was taken out of service and has since been used by the Fraunhofer-Institut für Integrierte Schaltungen from Erlangen. Two identical Bundeswehr listening posts stood on elevations along
